Lie on your back with your knees bent and feet flat on the ground, roughly 6-8 inches away from your hips. Press the back of your arms into the floor and lengthen your neck.

Press through your feet and lift your hips off the ground while keeping your spine in a relatively neutral position. Squeeze your glutes firmly at the top, then lower down slowly.

You can perform this exercise for repetitions or hold the top for a predetermined time (such as 30 seconds). The critical thing to remember is that your glutes must drive the action, not the lower back.
